WILLIAM L. GASS AND HARRY JACKSON, OF NEW YORK, N. Y.

ME CHANICAL Application filed March 3,

To all whom it may cmccrn:

Be it known that we, WILLIAM L. GAss and HARRY JACKSON, both citizensofthe United States, and residents of the city of New York, borough ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Mechanical Movement, of which the following is a full,clear, and exact description.

This invention relates to mechanical movements, and more particularly tomechanism for converting a rotary movement into a reciprocatory one.

More specifically, the invention relates to mechanism of the classdescribed comprising a rotatable, driven member having an eccentric, anannular member operable by said eccentric, and means for connecting saidannular member with a reciprocable member, so that the rotary movementof the driven member serves to reciprocate the reciprocable member.

An object of the invention-is to provide mechanism of simple and durableform, for converting a rotary movement into a reoiprocatory one, whichis efficient in opera tion and which is inexpensive to manufacture.

A further object of the invention is to provide mechanism of the classdescribed, which lends itself readily to inexpensive and easy shopconstruction, and by means of which a perfect alinement of the partscan. be effected without difficulty.

The invention consists in the construction and combination of parts, tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is a sideelevation of our invention; Fig. 2 is a longitudinal section of the sameand Fig. 3 is a side elevation partly in section, showing a detail ofthe invention, of modified form.

Before proceeding to a more detailed explanation of our invention, itshould be clearly understood that the same can be advantageouslyemployed in most forms of mechanism in which it is necessary to converta rotary into a reciprocatory movement.

MOVEMENT.

1908. Serial No. 418,968.

For example, it can be usefully employed in connection with pumps of thereciprocating type, steam engines, prime movers, and the like. We employa rotary member having formed thereon an integral eccentric ring, inwhich is movably arranged a further ring or annular member, which isconnected by means of a suitable bracket and a wrist pin with the memberto be reciprocated. The rotation of the driven member through theeccentric, effects a reciprocatory movement of the annular membercontrolled by the eccentric, which in turn is transmitted to thereciprocable member to be driven, in accordance with the well-knownprinciple of eccentric movement.

Referring more particularly to the draw ings, we provide a rotatablemember 10, preferably cast, or otherwise fashioned from suitablematerial, in the form of a disk. The member 10 has a central hub 11 bymeans of Which it is mounted upon a shaft 12. The latter is journaled insuitable bearings 13 or is otherwise rotatably mounted. The mem ber 10may be driven by means of the shaft 12, or may be provided peripherallywith teeth 14 adapted to mesh with the teeth of a pinion 15 rigidlycarried by a shaft 16 journaled in bearings 17 suitably positioned topermit the operative engagement of the pinion with the teeth of thedriven member 10. The latter may be actuated by means of the shaft 16,which may be power-driven or otherwise operated in any suitable manner.At one side, the member 10 has formed thereon an integral eccentric ring18 which encompasses the hub 11. The ring 18 is interiorly machined toform a shoulder 19. An annular member or ring 20 is arranged within theeccentric ring 18 and has a peripheral rim or bearing face 21 of aneasily fusible material such as Babbitt metal or of any other materialadapted to the purpose. The annular member 20 abuts against the shoulder19 and is held in position within the eccentric ring 18 by means of aretaining ring 22 suitably fastened in position at the outer rim of thering 18 and extending inwardly beyond the rim. The engagement of theBabbitt metal rim 19 with the eccentric ring 18 is a bearing one. Theannular member 20 has an inner peripheral groove 30 formingoil-retaining means, and it is further provided with oil-holes 31 whichpermit the passage of the oil to the wearing surfaces. desired, theBabbitt metal rim 19 at the outer surface, may have oil grooves 23 ofany preferred or common form. The annular member 20 has rigidly securedthereto, by means of bolts 24: or in any other suitable manner, abracket 25 having a wrist pin 26 engaging ighe cross-head 27 or otherreciprocable memer. centric ring 18 travels about the center of rotationof the member 10, and thus reciprocates the cross-head 27 through theannular member 20, the cross-head, of course, be ing constrained to movein the direction of its length. In this way, the rotary movement'of thedriven member is transmitted to the cross-head or other reciprocablemember in a backward and forward movement. If so desired, the oppositeside of the member 10 may be rovided with an eccentric ring 18 and thelatter can be used to reciprocate another member, such as the cross-head27.

In Fig. 3 is shown an annular member 20 of modified form having at theseparated oints, peripheral recesses 28. in which are oosely arrangedwear shoes 29. The latter are adapted to engage at the inside of theeccentric ring 18 and are controlled by means of bolts 30 having locknuts 31 By means of the bolts 30, the shoes 29 can be adjusted as theywear. If so desired, the bolts 30 and the lock nuts 31 can be dispensedwith and the shoes adjusted by placing shims 82 underneath the same.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. In combination, a rotatable member having an eccentric, a membermovably held by said eccentric and having a lubricant reservoir, aretaining ring secured to said eccentric and extending over said member,a reciprocable member, and means for operatively connecting said memberand said reciprocable member, said member having means for directinglubricant from said reservoir to the wearing surfaces.

2. In combination, a rotatable member having an eccentric formedthereon, said eccentric having a shoulder, a circular member arrangedwithin said eccentric and engaging said shoulder, a removable retainingring mounted upon said eccentric and partly over said circular member,said circular member As the member 10 is rotated, the e0 If so having abearing rim engaging at the inside of said eccentric, a bracket uponsaid circular member and having a wrist pin, and a reciprocable memberhaving a pivotal connection with said wrist pin.

3. In combination, a rotatable member having an eccentric ring formedthereon, said eccentric ring having at the inner side a shoulder, anannular member arranged with in said eccentric ring and engaging saidshoulder, a removable retaining ringmounted upon said eccentric ring andextending partly over said annular member, said annuiar member having anouter rim of an easily fusible metal, engaging at the inside of saideccentric ring, a bracket rigid with said annular member and having awrist pin, and a reciprocable member having a pivotal connection withsaid wrist pin, said annular member constituting a lubricant reservoir.

4. In combination, a rotatable member having an annular eccentric formedthereon, an annular member movable in said eccentric, a cross-head, andmeans for movably connecting said cross-head and said member, saidannular member having at the inside a peripheral groove constituting alubricant reservoir, and being provided with openings therethrough topermit the passage of lubricant from said groove to the Wearingsurfaces.

5. In combination, a rotatable memberhaving an eccentric ring formedthereon, an annular member arranged within said eccentric ring, meansfor retaining said annular member within said ring, said annular memberhaving an outer rim of easily fusible metal engaging at the inside ofsaid eccentric ring, a reciprocable member, and means for operativelyconnecting said reciprocable member and said annular member, saidannular member, at the inside having a peripheral groove constituting alubricant reservoir, and being provided with openings therethroughserving to conduct lubricant to the outer surface of said rim of fusiblemetal. In testimony whereof we have signed our names to thisspecification in the presence of two subscribing witnesses.
